Trục khuỷu (The Crankshaft)

The crankshaft is a key element of the crank mechanism in an internal combustion engine, which converts the reciprocating motion of the pistons into rotational motion. It is a long shaft with many cranks (cranks) to which connecting rods are attached. The connecting rods, in turn, are connected to the pistons, which move up and down in the cylinders.
